SADIRON.

Application filed May 12, 1919.4

T0 all 'whom t may concern:

Be it known that l, MICHAEL BROWN, a citizen of the United States, and a resident of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Sadirons, of which the following is a specification.

rThe present invention relates to improvements in sad irons and more particularly to gas-heated irons.

The main object ofthe invention is to provide an iron ofthe type mentioned which is simple in construction, efficient in operation and which can be manufactured on a commercial scale or, inother words, one which is not so diiiicult to produce as to`be beyond the reasonable cost of such an article.

Another object of the invention is to so construct the iron that it may be used as a heater by. detaching some ofthe elements thereof, the whole being so constructedthat the elements to be detached can be conveniently removed and again placed ,in position, when needed.

A further object of the invention is to so design the iron that it can be easily taken apart and assembled, the uniting elements thereof beingirremovably mounted upon certain elements of the same, so that they cannot be lost or niislaid.

A still further object of the invention is to provide a sad-iron which may be quickly heated to the desired temperature, mains taining a substantially even temperature, its burner being constructed so as to be economical in fuel consumption.

Another object of the invention is to so design the iron bottom that it is evenly heated by theheat delivered to the same.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described., pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several partsv and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

of the invention are illustrated in the accompanying drawings, in which Figure l is a top plan View of a sad-iron constructed in accordance with the present invention, part of its handle being broken away to more clearly show the construction of the parts below the same; Fig. 2 is a section taken on line 2 2 of Fig. 1, showing also a stand for the iron; Fig. 3 is a section taken on line 3 3 of Fig. 2; Fig. 4 is a top plan view of the bottom of the sadiron; Fig. 5 is a vertical section taken through the gas supply connection; Fig. 6 is a section taken on line 6 6 of Fig. 5; Fig. 7 is an elevation, partly in section, of a modification of the gas supply connection; Fig. 8 is aplan view of the stand used in connection with the iron; and Fig. 9 is a side elevation of part of the iron and stand used as a heater.

Referring now first to Figs. 1 to 4, inclusive, the numeral 10 indicates the body of the iron, and the numeral 11 the bottom or base thereof. The body is made in the form of a chambered casting, provided .with interior lugs 12, which project below the same and are seated in recesses 12 in the base 11. rI'he bottom is provided all around with an upwardly extending flange 13,V that is spaced from the body 10, whereby an air inlet passage 14 is formed. Adjacent the closed top 15 of the body there is formed in the body a plurality of openings 16, through which the products of combustion are allowed to escape. In the top 15 is formed a longitudinal recess 17, covered by a member 18, the latter having along its longitudinal edges upwardly and outwardly extending curved wings 19, forming a shield that serves to deflect from the hand grasping the handle 2O the hot air and gas escaping from the iron. The shield is held upon the 1body 10 by a centrally disposed exteriorly screw-threaded bushing 21. rlhis bushing is provided at its lower end with a head 22, seated in a recess 23 in the underface of the top 15, its screw-threads meshing with those of a bore 24C in the member 18.

The base, body and handle are held together by a bolt 25, that is threaded into a centrally disposed boss 26 on the base 11. This bolt extends vertically upward through the bushing 21 and through the handle 20, its upper end being provided with screwthreads 27, in mesh with those of a wing nut 28, that abuts' against the face 29 of the handle. The nut extends through the handle and has a peripheral groove 30, into which reach lugs 31, that are formed upon the handle, preferably, by stamping, there'- by preventing a disengagementV of the nut from the handle.

From the inner face of the top`15 project downward inclined tubular burners 32, communicating.with'the recess 17. These burners are directed toward pockets 33 in the upper face of the base 11, the gas jets issuing from the burners striking or impinging the said pockets.v The side walls 34 of the pockets on the sides of the base gradually decrease from their outer ends 35 toward the longitudinal center line of the iron base, so that the said pockets are open near the said center line. The end pockets on the bottom, on the other hand, are open adjacent the ends ofthe iron, there being two end pockets adjacent each end of the iron, as clearly appears from Fig. 4'of the drawings, and between each setof said end pock ets there is provided a channel 36. rThese channels are disposed in the longitudinal center line of the iron. In this manner the heat is properly distributed over the surface y of the bottom, the latter being hottest at its end points, the flames being directed by the walls of the end pockets toward the said end points and fresh air traveling throughthe channels 36 toward the flames;

The liron body is provided at one of its ends with the usualv gas supply connection, consisting of a tube 37, having a nipple 38 at one of its ends and a nozzle 39 at its other end. This nozzle registers with a lon- '.gitudinal bore 40 inthe iron body, said bore J threaded into the iron body. Spacing nuts .Y zle 39 to be adjusted, at will.

43 and clamping nuts 44 mesh with the bolts 42, said nuts being disposed on opposite faces of the flange 41, thereby permitting the distancel between the bore 40 and noz- Over the nipple 38 is drawn a gas supply hose 45. A sleeve 46 upon the tube 37 serves to actuate a-valve, the construction of which will be described hereinafter.

The operation of this device is as fol lows The gas and air are supplied to the recess 17, which constitutes the burnerbody,

the mixture passing through the burners, where it is supplied with the necessary air through the air inlet passage 14,' so thata perfect combustion results. y

In order toV dismantle the iron, first the wing nut 28 isv unscrewed from the bolt 25, therebyY permittingthe handle and the nut, as a unit, to be removed from the body 10. The body with the shield thereon may then be taken off the base 11, the shield being removed from the body by unscrewing the bushing 21. A

The as supply connection is shown in detail in ligs. 5 and 6 of the drawings. This connection comprises the tube 37, the bore 48 of which extends eccentrically therethrough, communicating at the outer end with the nipple 38 and at the inner end with the nozzle 39. The gas supply may be regulated by a valve 49, in the form of a screwthreaded bolt, that extends' into the bore 48, its threads meshing with those ofA a bore 50, extending substantially parallel to the major portion ofthe bore 48. To this bolt is lixedly secured a pinion 51, meshing with an v internalgear 52- upon the sleeve46,-that is rotatably mounted upon the tube 37. By rotating the sleeve in one or the other direction, the bolt 49 is caused toproject more or less into the bore 48, thereby regulating the gas supply. 1

A modification of the gas supply connection is 'shown in Fig. 7 of the drawings,'dif fering from that illustrated in Fig. 2,in that its flange 41 is looselymountedfupon the tube 37, it being clamped against a shoulder 53 on the nozzle 39 by a wing nut 54,which meshes with the screw-threadedy portion 55 ofthe tube 37. This constructionY permits the tube 37 with itsnozzle and nipple to'be swung to any desired position withoutv detaching the flange 41 from the body 10 of the iron. The purpose of this arrangement will appear hereinafter.

The hot iron may be placed uponastand 56 (Fig. 8), when not inuse. VThis'fstand comprises a plate member 57, having an upf wardly extendingii'ange 58 all around, said flange being of a configuration and size that the iron base 11 properly tsinto the same. From the underface of the platemember project downward supporting legs 59, which are so arranged that they fit into the body 10, when its base 11 isremoved therefrom. 110 The purpose of this arrangement will ap-` pear presently.

If it is intended to use'the iron asa heater, for instance as a cooker or toaster, its han dle and base are'removed, and the gas supply 115 tube 37 shifted around 180 degrees. The body is then inverted so as to rest upon the shield thereof, (Fig. 9). Thefstand56 is then put upon the body 10, its legs 59 projecting into said body. These legs'are so 120 disposed, that theplate member 57 of the stand is held a' substantial distance above the said body, to permit a `circulationjof air therethrough whereby a Iperfect combustion of the gas mixture'isobtained; The articles 125 to bev heated, cooked or toasted are placed upon the stand.

What I claim is 1. A sad iron, comprising a base, a chambered body thereon having a longitudinal recess in its top, a member covering said recess provided with upwardly and outwardly extending wings projecting over said top, a screw-threaded bushing uniting said member and said body, tubular burners within said body communicating with said recess, a gas supply connection leading to said recess, a handle placed upon said mem* ber, a screw-threaded bolt fixed to said base extending through said bushing and handle, and a nut on said handle in engagement with said bolt for uniting said base, body and handle.

2. A sad iron, including a base, a chambered body thereon having a longitudinal recess in its top, a member covering said recess provided with upwardly and outwardly extending wings projecting over said top, a screw-threaded bushing uniting said member and said body, a handle placed upon said member, a screw-threaded bolt fixed to said base extending through said bushing and handle, and a nut on said handle in engagement with said bolt for uniting said base, body and handle.

3. A sad iron according to claim 2, comprising means for spacing said body from said hase to provide an air passage.

4. In a sad iron according to claim 2, said body being provided with lugs projecting below the same and resting upon said base, so as to space said body fromv said base.

5'. A sad iron, including a chambered body having a longitudinal recess in its top, a member covering said recess provided with upwardly and outwardly extending wings projecting over said top, and burner tubes made integral with said body communicating with said recess.

6. A gas supply connection for sad irons, comprising a cylindrical body having an eccentrically disposed gas conduit, a screwthreaded bolt projecting into said conduit, a sleeve rotatably mounted upon said cylindrical body having an internal gear, and a pinion fixed to said bolt in mesh with said 0fear.
